Removing this resource from your configuration 45 will remove it from your statefile and management, but will not destroy the subnet. 46 You can resume managing the subnet via the AWS Console. 47 48 ## Attributes Reference 49 50 The following attributes are exported: 51 52 * `id` - The ID of the subnet 53 * `availability_zone`- The AZ for the subnet. 54 * `cidr_block` - The CIDR block for the subnet. 55 * `vpc_id` - The VPC ID. 56 * `ipv6_association_id` - The association ID for the IPv6 CIDR block. 57 * `ipv6_cidr_block` - The IPv6 CIDR block.
